Is Savage between 216 and 32? I'm an expert on southern Howard County, but don't know anything east of Scaggsville or north of Laurel very well at all.
The Isaac Walton league I belong to (in Damascus) has 50/100 yard rifle ranges and pistol ranges with targets movable from 10-50 yards. Outdoor, with covered shooting area. Also has a trap range and several skeet yards. Yearly dues to become a member are the only fees; at the Damascus location, some environmental work (trash pickup on roads, tree planting, etc.. usually on weekends) is also required the first year.
The Mt Airy Walton League has, I hear, 200 yard rifle range I hear. Also supposed to have a good trap-shooting schedule.
The Carroll County landfill has the Hap Baker shooting range, but I've never been there; they had a major fire last February and I'm pretty sure the rifle ranges are still closed - but the handgun range might be open.
